Description

Floating net cage capable of being mutually communicated

Technical Field

The utility model belongs to box with a net field of breeding fish, specific theory relates to a floating box with a net that can communicate each other.

Background

The net cage fish culture is a fish culture mode that a box body in a certain shape is assembled by using materials such as synthetic fiber net sheets or metal net sheets in a natural water area, fishes are cultured in the box body at high density, the environmental conditions suitable for the growth of the fishes are maintained by means of water exchange inside and outside the box body, and fry culture or commercial fish culture is carried out by using natural baits or artificial feeding. At present, the net cages in the cultivation production are various, and can be fixed, floating and sinking according to the arrangement mode, wherein the floating net cages are most widely adopted and are commonly used in reservoirs and lakes with deeper water bodies and smaller storms, shallow seas, inner bays and other areas. Compared with a fixed net cage, the floating net cage can float along with the change of the water level, so that the effective volume is kept unchanged.

In the actual cage culture process, when the temperature is high, moss and macroalgae are easy to adhere to the surface of the netting, and mass propagation and growth of the aquatic plants can seriously block meshes, so that excrement, residual bait and the like are retained in the box body, water exchange between the inside and the outside of the cage is reduced, the culture water environment is deteriorated, and even pathogenic bacteria are bred to influence the health of the fish body. Usually, the method of replacing the net is adopted to solve the problem, all the fishes in the net cage need to be fished out in the actual operation process, or the net needs to be collected and poured into a new net cage, so that the fishes are easily frightened and even have mechanical damage.

Disclosure of Invention

The utility model aims at the not enough of above-mentioned prior art, the utility model aims at providing a floating box with a net that can communicate each other avoids the tradition to fall the damage of fish in-process to the fish body, the change and the routine maintenance of the box with a net of being convenient for.

To achieve the above object, the solution of the present invention is: a floating type net cage capable of being communicated with each other comprises a floating type net cage body and a communication device thereof. The novel net cage is characterized in that one or a plurality of communicating devices are arranged on a side net of the box body of the net cage, and each communicating device comprises a frame structure and a netting and is of a rectangular groove-shaped structure; the frame structure comprises a net cage opening frame, a bottom frame, vertical rods and transverse rods, and the netting is wrapped at the bottom and the left side and the right side of the frame structure.

The frame structure is made of stainless steel or hard plastic.

The frame structure composition units are movably connected and can be folded and attached to the box body of the net cage after being folded.

Furthermore, a lifting rope is tied to the bottom frame of the frame structure, and the net cage is folded and unfolded through the retraction of the lifting rope.

Furthermore, the telescopic rods on the outer side edges of the bottom frames of the frame structures have a telescopic function, and the width of the front end of the communication device can be adjusted.

Furthermore, the floating net cages capable of being mutually communicated have the communication devices between the adjacent net cages aligned with each other, when the fish pouring work is carried out, the width of the front ends of the communication devices at the two sides is firstly adjusted, the two communication devices are unfolded and nested together, and the cross rods are mutually fixed, so that the communication between the adjacent net cages is realized. After the fish is poured, the communicating device is folded and is attached and fixed on the side edge of the net cage, so that the net cage is in a closed state.

The utility model has the advantages that: the communication between the adjacent net cages can be realized quickly, and the operation method is simple. When the fish is poured, the fish can independently swim into the target net cage through the connecting channel by utilizing the food calling or driving mode, and the damage to the fish in the fish pouring process of the traditional net cage is avoided. Meanwhile, the communication device is foldable, is tightly attached to the wall of the net cage after being folded, can serve as a part of the net cage body, and prevents fish from running.
